Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates a casing which includes end members orheads 11 which are connected by independent freezing units 12. The units 12 are removably secured between the heads 11 by any suitable'means and each unit comprises a vertically disposed elongated casing 13, closed to provide a freezing compartmentl l. At each end, theunits 12 are provided with spacing blocks 15 Which receive screws or bolts 16' extendingthrough the head 11. The freezing compartments 14 of the units 12 are in communication with one another through nipples 15 so as to provide for a circulation through the Each freezing unit 12 further includes a plurality of containers 16 which are shown as cylindrical. Normally the casing 10 is so positionedthat the freezing compartments 14 will be arranged in horizontal spaced rela-,

tion while the containers are vertically disposed and are open at the top as shown in Figure 3 of the drawings. Extending through one of the .heads 11 and communicating with one end of one of the freezing compartments. 1

compartments 14 is" a pipe 17. This pipe communicates with a pipe 18 which extends to a suitable supply of brine or other freez- 21 extends from the opposite endof the casing and hasits inner end dis osed within a ing solution. The 'ipe 18 is mounted in a bearing 22 carried by the ad acent head 11,

bearing 23 so that a pivotal support is provided for this end of the casing. The casing may thus,be moved so as to dispose the freezing compartments in vertical spaced relation with the containers horizontallyarranged. The ipe 21 isin communication with one end 0 one of the freezing compart' .ments by means of a pipe 23', .while also extending from the plpe 21 is a pipe 24 which may lead to the brine supply and which may be in communication with a pump 25 bymeansof'apipe' 26. The pipes 18 and 21 are provided with suitable packing glands 27 so that the inner sections of these pipes. may rotate with the casing and a while the pipe 21 also is mounted within a leak-proof joint be provided. The pipes 18 and 24 are provided with controlling valves 28 and 29 respectively. The outer freezin units 12 are provided with discharge an vent cocks 30 and 31 respectively. Awater supply pipe 32 communicates with the pipe 18 and is provided with a controlling valve 33. y

The outer freezing units 12 are in communication with one another at one end of the casing by means of a substantially U- shaped pipe 34, the latter. being provided wit valves 35 between which isa. graduated transparent section 36' so as to provide a gauge or indicator. The pump 25 is provided with a flexible pipe or hose 37 which may be dctachably connected to the drain cock 30..

The containers 16 are filled with the confection to be frozen, afterwhich the valves 28 and 29 are opened so as topermit the brine to flow through the freezing compartments 14. When the contents of the con- 'tainers begin to freeze, a stick-like handle 38 is inserted within the confection 39 as shown in Figure 3 of the drawings, the bottom of the confection being suiiiciently stifi' to prevent thestick 38 from moving upward due to the difference in specific gravity. After, the freezing operation, the hose 37 may be connected to the drain cook 30, and the pump operated to suck the brine from the freezing compartments and force the same out-ward through the pipes 26 and 24 back to the source of supply, the vent cook 31 being opened to prevent the formatlon of a vacuum. If desired, the casing may be moved pivotally to the position shown in Figure 5 of the drawings so that the freezing units are vertically spaced and the brine permitted to drain into areceptacle 38' lo-- cated beneath the casing. After the brine has been removed from the freezing com-' partments', the cooks 30 and 31 are closed and the cook 33 opened so as to permit water to flow into the freezing compartments around the containers for the purpose of forming the frozen confection, whereby the latter may be removed. To prevent'undue meltingor softening of th'e'confection, the

water is introduced to the freezing units successively or one at a time. For this purpose the indicator 33 is graduated in accordance with the hEIghlLOf the respective freezing units when the latter are verticallyspaced and as soon' as water reaches the first graduation upon-the transparent pipe 36, the

valve 33 is closed and the. contents of the containers of the lowermost unit are re-" posed moved. The valve 33 is then opened and water permitted to enter the next succeedmg freezing unit and the contents of this unit removed and so on until the contents of the entire apparatus have been ,removed.

Having described the invention what is claimed is 1. A machine for making frozen confections com rising a casin a plurality of horizontal y spaced norina y vertically disments included in the casing, separate normally vertically disposed containers within each of the compartments, means to intro- .duce a freezing solution into the freezing compartments to act upon the contents of the containers; means topermit of rotation of the casing to dis ose the freezing compartments in vertica y spaced'relation and facilitate draining, means to successively introduce a softening liquid into the freezing compartments to release the contents of the containers and means to indicate introduction of the softening liquid within each of the compartments.

2. A machine for making. frozen confections comprising end members, a plurality of horizontally spaced separate freezing units removably secured between the end members, each unit comprising a vertically disposed elongated freezing compartment and separate containers within each compartment, means providing communication between the compartments, means to introduce. a freezing solution within the compartments to act upon the contents of the containers, means for pivotally supporting the casing to position the freezing compartments in vertically spaced relation, means to successively supply a softening liquid to the freezing compartments to release the contents of the containers and means to indicate the introduction of the softening liquid within each ofthe com artments.
